Resistant to thermal cycling and able to provide a seal that’s helium-leak tight, the Pop-A-Plug® CPI/Perma Tube Plug is the safe, effective, and reliable solution for heat exchanger tube leaks. Rated to 1000 PsiG (68.9 BarG), the Pop-A-Plug® CPI/Perma Tube Plugging System takes seconds to install and its broad expansion range fits multiple gauges. Fewer plugs are required, reducing inventory and costs. Controlled and repeatable installation minimizes installer fatigue and protects against damage to tubesheet ligaments and adjacent tubesheet joints, extending the life of heat exchangers and reducing costs for retubing. Kits include ten (10) plugs and one (1) Go/No-Go Gage.
